My launch-window iPhone 5's battery was clearly fading. I could barely make it a day on light use, and the device would frequently go from ~40% charge to single digits.
Honestly, I was hoping to not have to do this and just replace the device with an iPhone 6 (or whatever its called) in September, but the poor battery life became too aggravating.
Mostly good. One end of the case opener tool broke while trying to gently pry out the battery. Once I did get the battery out, I was able to gracefully remove the broken piece.
One thing the video doesn't do a good job of telling you is how tiny the screws are -- they are absolutely the smallest screws I have ever laid eyes on.
Speaking of the video, I opted to not remove the entire display assembly. I simply held the display up while I removed the battery and its' connector. The video has you removing the display which has a fair amount of screws and touch-points.
Finally....and unfortunately.. I'm not sure if replacing the battery made that much of a difference. It helped for sure, but not an incredible amount.
Just take your time and you'll be fine. Consider getting a better case opener tool, though. I am considering an iSesamo tool for when I replace the battery in my wife's phone.
Additionally, have a LOT.. and I mean A LOT of direct light when you perform this repair. The screws.. holy $hit are they small.
